OPS300 Motion Correction
This item gives information about the new “Motion correction” setting added in the OPS300 device.
- Aim of the “Motion Correction” setting:
The aim of the “motion correction” setting is to correct a “comb effect” sometime visible on OPS300 device.
From the front panel, a new setting has been added in the Menu/Image/Advanced section.
- Typical case:
The “comb effect” appears only with moving interlaced input pictures, with
vertical scaling, more with medium contrasted images and mainly with inter-
laced output format.
The default value of this setting is 0 for standard motion correction, and can be increased up to 100 for full-
motion correction.
The correct level must be adjusted according to the image, preferably not at maximum, in the following
examples around 80 or 90.
- Examples:
Here is an example of a worst case scenario, using an analog HD-YUV input signal from an HD camera run-
ning in 1080i 50Hz, split in two layers side by side (with and without correction), displayed in interlaced 1080i
50Hz frame locked on the input, with a few scaling.
The camera is panning over a medium contrasted scene as viewed here:
